What Is It?

Selenium is a trace mineral naturally occurring in the soil, in certain foods, and very small amounts can be found in natural water sources.

Selenium’s main role is acting as an antioxidant and has many benefits to the body. Selenium is also a chief component of the molecules which are necessary for your body to be able to create and use thyroid hormones, called ‘selenoproteins’.

Selenium also plays an important role in prostate health, helping to maintain healthy levels of Prostate-Specific Antigen (PSA) which is the marker for prostate cancer.

Selenium acts as a powerful antioxidant and defends against oxidative stress. There is also a strong correlation between serum levels of Selenium and a reduced risk of several types of cancer.

Studies show that foods high in Selenium may prevent cancer by helping with DNA repair, preventing cancer cells from replicating and by reducing free radicals in the body [1].

This mineral is such an important factor in supporting the immune system that it’s a key ingredient in our Immuno Multi formula.

Selenium-rich foods (and the selenoproteins that they help form) can also prevent platelets from aggregating (which improves blood flow), prevent oxidative damage to cells (e.g. prevent the oxidative modification of lipids) thereby reducing inflammation and lowering the risk of cardiovascular disease [1].

People with low levels of serum Selenium have been shown to be at higher risk of cardiovascular disease. For these reasons, experts have suggested that Selenium supplements could reduce the risk of cardiovascular disease or deaths associated with cardiovascular disease.

→ REGULATES THYROID FUNCTION

Selenium is probably most well-known for its role in maintaining thyroid health since it works together closely with Iodine – another important trace mineral.

Concentrations of Selenium are higher in the thyroid gland than anywhere else in the body. It helps to regulate and recycle our Iodine stores and is needed to produce the critical thyroid hormone T3, which regulates metabolism.

‘Selenoproteins’ protect the thyroid gland when we are under stress. They help flush out oxidative and chemical stress, and even social stress – which, as most of us have experienced, can cause many negative reactions in our body.

Signs, Symptoms, and Causes of Selenium Deficiency

A selenium deficiency is generally observed in areas where the soil does not contain much of it and the mineral content in soil can differ dramatically depending on location.

Even in food sources, the amount of Selenium is largely dependent on soil conditions that the food grew in. Therefore, even within the same food, levels of selenium can vary widely, and the mineral’s benefits may be more prominent in crops grown in certain locations more so than others.

Health Experts are becoming increasingly concerned as evidence suggests that a decline in blood Selenium levels is occurring in parts of the U.K. and other European Union countries. The worry is with several potential health implications that can result due to a deficiency in this mineral.
